I was informed by a local ham that he was unable to link to another node through our Allstar repeater, node 28515. When I tried it I got confirmation tones followed by "connection to node number nnnnn was unsucessful". After verifying info information per Allstar Link.org suggestions in the article [Cannot Receive Connections or Make Connectios to Other Allstar Nodes] including proper port forwarding I was only able to get connections and commands to work intermittently.
